As you can see, my current attempt at an 'ebook promo page' is pretty crude: http://cloudmigration.guide.
I'm about to try out all the various WPMUDev social marketing tools (Hustle etc.) and improving this page seems an ideal starting point.
My ideal scenario is i) some kind of page that pops when you visit it, but it's still part of the site, and then ii) you have to share the link / subscribe to access the download, etc.
What tools should I consider using and how to achieve this scenario .. any help much appreciated..
